A:AnswerMine didn't work at all after the update. Ive got the Galaxy note 8. After reading several blogs with others having the same problem, one person had a simple fix that I tried and it worked. I guess the update changes settings. All I did was went into settings and turned the NFC back on and my case came back to life. I hope this helped. Good luck
A:AnswerNormally, when the case cover is closed, the LEDs come on and will display your time. When you get notifications, the icon will appear depending on what it is and then it should go away. If you have issues, I would recommend to take it back or contact Samsung.
A:AnswerI have a ZAGG curve screen protector on mine... No problem with the fit and this case...
I would assume that the same would apply to any quality screen protector.
